Serrin-Type Overdetermined Problems: an Alternative Proof

2008

We prove the symmetry of solutions to overdetermined problems for a class of fully nonlinear equations, namely the Hessian equations. In the case of the Poisson equation, our proof is alternative to the proofs proposed by Serrin (moving planes) and by Weinberger. Moreover, our proof makes no direct use of the maximum principle while it sheds light on a relation between the Serrin problem and the isoperimetric inequality.

Stability of radial symmetry for a Monge-Ampère overdetermined problem

2008

Recently the symmetry of solutions to overdetermined problems has been established for the class of Hessian operators, including the Monge-Ampère operator. In this paper we prove that the radial symmetry of the domain and of the solution to an overdetermined Dirichlet problem for the Monge-Ampère equation is stable under suitable perturbations of the data. © 2008 Fondazione Annali di Matematica Pura ed Applicata and Springer-Verlag.

Spatial Structures of the Philippines: Urbanization and Regional Inequalities

2017

This chapter examines the fundamental spatial structures of the Philippines. It defines the role and organization of the different levels of the administrative hierarchy (provinces, regions, cities and municipalities) down to the barangay and sitio/purok levels. This leads to the definition of the “urban” in the Philippines and the rise of urbanization in recent decades, from the original urban settlements of the Spanish era, with their patterns following the same rules as in Latin America (fort, church and plaza), to today’s cities. Forms of housing have evolved over time, from the archetypal bamboo/nipa hut (bahay kubo) and the urban stone and wood house of the elites (bahay na bato), now…

Young Lads and Old Tars: Changing Age Structure of the Nordic Sailors, 1750s–1930s

2022

AbstractThis article analyzes the changing age structure of Swedish and Finnish sailors for almost 200 years. We show that the proportion of the youngest men increased during the age of sail (i.e., the older technology). The average age increased significantly during the early twentieth century as steam (i.e., the newer technology) replaced sail in Nordic shipping. Thus, a technological revolution did not displace the older workers, but rather diminished the demand for the younger ones. This study shows, however, that technological changes were not the only drivers of changes in the age structure of Nordic sailors. Institutional and societal changes also played an important role, though the…

Mating (marriage) patterns and economic development

2011

This paper looks at the relationship between economic development and mating (marriage) patterns in the very long run. For this purpose we introduce the Goldin and the Kuznets curves which relate female labour and income inequality with economic development respectively. To some extent, the Goldin and the Kuznets curves have followed opposite paths, which in turn, could illustrate how economic development has had an impact on mating (marriage) patterns, and thus household formation. Convergence in mating patterns among hunter-gatherers across societies vanished after the Neolithic revolution. Then, African polygyny and the ‘European’ marriage pattern developed into the most significant exce…

Inequality and Growth in a Developing Economy: Evidence from Regional Data (Spain, 1860–1930)

2020

ABSTRACTThis article measures inequality at the provincial level in Spain for different benchmark years between 1860 and 1930. It then empirically assesses the relationship between economic growth and inequality. The results confirm that, although growing incomes did not directly contribute to reducing inequality, at least during the early stages of modern economic growth, other processes associated with economic growth such as the rural exodus to urban and industrial centers, the demographic transition, and the spread of literacy, among others, notably improved the situation of the bottom part of the population.

Introduction: A New Look at the Origins of Economic Growth and Regional Inequality

2018

The contributions to this special issue share important themes and methodologies in their quest to explicate economic development and its effects. Nonetheless, each area under examination has its own peculiarities and warrants its own scope of analysis. The result is a special issue that pursues an innovative line of research, exploring parallels and contrasts in economic growth and inequality based on new data at the regional, rather than simply the national, level. The authors are grateful to the following institutions for their financial support of the research in this special issue of The Journal of Interdisciplinary History: (1) European Union (EU— Jean Monnet Action); (2) ICREA—Genera…

A Latin American Casanova? Sex, Gender, Enlightenment and Revolution in the Life and Writings of Francisco de Miranda (1750–1816)

2022

This paper looks from a gender perspective at the elusive figure, complex personality and myth of Francisco de Miranda, enlightened traveller and Precursor of Latin American independence. By analysing Miranda's personal archive as his own carefully crafted creation, it pursues three closely connected issues insufficiently interpreted in historical perspective: the forms of masculinity he embodied and those from which he distanced himself, his connections with women and the role that gender played in his assessments of the countries he visited and wrote about. Miranda's trajectory and self-image trace an evolution (from mondain seducer and enlightened reader and thinker, to revolutionary sym…

Doña Marina, otra vez. Las contradicciones de la propuesta de Inés M. Stranger en Malinche

2019

La obra Malinche, de Inés M. Stranger, configura una propuesta de reescritura de la Malinche como figura mítica incorporada al imaginario cultural hispanoamericano, que perdura hasta la actualidad. Es común el empleo de esta figura en diversos autores contemporáneos que abordan cuestiones relativas a las identidades nacionales latinoamericanas en sus textos. Algunas autoras han utilizado, además, este personaje para elaborar una reescritura del mito con perspectiva crítica, en relación al modo en que este califica a un modelo de mujer indígena con toda una serie de significados negativos. La obra de Inés M. Stranger a la que se dedica el presente trabajo tiene unos presupuestos similares. E…

Sexism, romantic love and gender inequality. A study of Latin American adolescents living in Spain

2019

Este trabajo examina el papel de los factores sociodemográficos como determinantes de las creencias y actitudes sexistas y las percepciones distorsionadas sobre el amor romántico, y analiza la relación entre el sexismo hostil y el sexismo benevolente y las creencias en mitos del amor romántico, según el Índice de Desigualdad de Género (idg), en una muestra de 203 adolescentes latinoamericanos residentes en Valencia (España). This paper examines the role of socio-demographic factors determining both sexist beliefs and attitudes and distorted perceptions of romantic love. Moreover, the relationship between hostile and benevolent sexism, and the belief in myths about romantic love is analyzed …
